How do I check the software version on the Iridium phone or Intelligent handset?

To verify the software version on the Iridium handset enter *#91# on the handsets' keypad.

To verify the software version on the LBT device (internal to the RST device) enter *#91# on the keypad of an Intelligent Handset.  This is also available on the Status tab of the Beam Management System software (in the ‘LBT Firmware’ field).
